At about a cubic millimeter in size, this camera is right at the size limit that the human eye can see unaided. The camera not only produces decent images but is also very cheap to manufacture — so cheap, in fact, that it is considered disposable."

Reasonably, 'at the size limit the human eye can see' to me means exactly that. There is a size below which you can't see unaided, no matter how close you bring your eye to the object because there's a limit to how closely your eye can focus. That size is at least one, and probably 2 orders of magnitude smaller than this camera.
